Title: Desulfurization of molten steel in ladle refining
Inventor: TAKAHASHI DAISUKE
IPC: F27D15/00
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To quickly and economically execute desulfurization by adding a slag-reforming agent into converter slag at the steel tapping time and reforming the slag composition having specified ratios or more of Al2O3 and CaF2 and specified ratio ranges of CaO/Al2O3 and CaO/SiO2. SOLUTION: The desulfurization by ladle-refining is applied to molten steel obtd. by converter-refining. The slag composition is regulated so as to be by wt.% >=30% Al2O3, >=5% CaF2, 1.1-1.8 CaO/Al2O3 and >=5.0 CaO/SiO2. The Al2O3 in the slag has an effect producing intermediate compound for lowering the m.p. of CaO. It is desirable to melt the slag-reforming agent by electrical heating together with the converter slag at the steel tapping time, and the converter slag contains <=1.5% P2O5 at the steel tapping time. Further, it is suitable to be >=9% MgO in the reformed slag and pretreated molten iron is preferably as the molten iron used for the converter-refining. The desulfurization can further be progressed by executing the slag reduction so that the slag composition becomes T.Fe+(MnO)<=1%.

IPC: H04L12/18
Filed: 1986-01-31
Abstract: PURPOSE:To unify the control method for 1:1 communication between terminals and that for communication among many points by holding a token in the originating side in case of 1:1 communication between terminals and holding it in an inter- multipoint communication controller in case of communication among many points. CONSTITUTION:In case of 1:1 communication between communication terminals 10 and 20, the terminal 10 sends a terminating side selecting command to the terminal 20. A command analyzing part 22 of the terminal 20 reports it to a token control part 23 that a token is not held. The response from the terminal 20 is sent to the terminal 10. A response analyzing part 12 reports it to a token control part 13 that the token is held if the reception response indicates that the token is held in the originating side. In case that the communication terminal 10 is the originating side and an inter-multipoint communication controller 20 is the terminating side, the analyzing part 22 of the terminal 20 reports it to the control part 23 that the token is held. The analyzing part 12 of the terminal 10 reports it to the control part 13 that the token is not held. In case that the inter-multipoint communication controller 10 is the originating side and the communication terminal is the terminating side, the analyzing part 22 reports it to the control part 23 that the token is not held, and the analyzing part 12 reports it to the control part 13 that the token is held.

Title: Absorption solution for absorption type freezer
Inventor: IIZUKA HIROSHI
IPC: C23F11/08
Filed: 1988-01-29
Abstract: PURPOSE:To suppress the decomposition of ethylene glycol thereby to suppress the denaturalization of an absorption solution and corrosion within the absorption type freezer by allowing the absorption solution including lithium halide and ethylene glycol to contain an additive consisting of at least a member or more selected from a group consisting of a urea compound, borate, molybdate or nitrate. CONSTITUTION:As an additive a urea compound includes a thiourea, borate includes lithium tetraborate, molybdate includes lithium molybdate, and nitrate includes lithium nitrate. Since the above described additive is contained in an absorption solution containing lithium halide and ethylene glycol, denaturalization of the absorption solution and corrosion thereof within the absorption type freezer are suppressed. Further, upon this occasion, in a case where the concentration of thiourea or the like added is too low, the suppression effect cannot be expected enough but at least 0.005wt.% of thiourea is required. Conversely, when the concentration of thiourea is too high, it cannot be dissolved completely and precipitation is generated and clearance corrosion is promoted. Therefore, it is desired that it does not exceed 0.1wt.%.

Filed: 1982-02-12
Abstract: PURPOSE:To avoid the dispersion of the density of recording due to heat storage phenomenon by connecting a parallel time-constant circuit consisting of resistors and capacitors in series with each heating resistor element in a facsimile, etc. CONSTITUTION:When making a recording for every line by supplying pulse voltage for a drive power source terminal 12 to heating resistor elements 7-1..., the potential of the contact point C between the heating resistor element 7-1 and a time-constant circuit 14-1 is moderately and exponentially raised by high-level  potential during the electrically energizing period for the contact point B between the heating resistor element 7-1 and a current control circuit 6-1 but it is  moderately lowered during the low level period in the cooling period. During  high-speed recording period, it is gradually raised as recording for every line  exceeds and converged to a certain value. Thus, potential difference between the  contact points B and C is also gradually reduced and converged and therefore, the dispersion in the density of recording due to heat storage phenomenon in a  short time range, entailed in high-speed recording of medium-tone pictures, can  be eliminated.

Abstract: PURPOSE: To make it possible to display a picture pattern at any place on a CRT by equipping a pattern memory, picture position processor, pattern assignment memory, and sequential reader for pattern assignment memories.  
     CONSTITUTION: By computing the position of a picture pattern on the CRT, picture position processor 3 outputs signals for picture position relation and horizontal occupancy length ΔX assignment via the address line and a pattern-code assignment signal of the pitcure pattern via the data line to pattern assignment memory 4. Data in memory 4 are read out line by line in sequence by pattern-assignment-memory sequential reader 5; data on ΔX are stored in horizontal occupancy length memory circuit 14, and data on pattern codes are in pattern memory 7. When the data on ΔX agrees with the value obtained by increasing a pattern sending clock from timing generating circuit 6, horizontal occupancy length comparator circuit 15 generates a coincidence pulse and a picture signal is sent out from memory 7 via shift register 8. As a result, assigning ΔX makes it possible to display a picture at any position freely.

Abstract: PURPOSE:To secure a safety for the operation control of a plant, by storing the contents of the operator's voice and then collating it with a certain voice reference data to decide whether the result of collation is identical to the check sheet or not for the monitor equipment of a reactor plant. CONSTITUTION:The aural signal supplied through the microphone 1 is amplified up to a prescribed level by the amplifier 21 and converted into a digital signal through the A/D converter 22. This digital signal is sampled by the digital data converter bus buffer 23 and with the sampling cycle of the pulse generator 24. Then the sampling value of the original voice is stored in the auxiliary memory device 5 through the CPU3. The contents of the operators's voice is collated with the voice reference data stored in the device 5 to be decided whether it is identical to the check sheet. In case the contents of the operator's voice is different from the check sheet, the continuation nonpermission signal is delivered for the operation, monitor and recording each to carry out immediately a correcting action. Then the second decision is given to the contents of the voice. In such way, a safety can be secured for the operation control at a reactor plant.
